Conclusion:
This contribution demonstrates how Zero Trust Architecture principles can be operationalized in a DT context, advancing a cybersecurity-by-design methodology suited for connected and dynamic industrial systems.
We proposed and implemented the architectural components and deployment steps adapted to industrial environments.
This approach demonstrates that assigning a dedicated realm and Policy Enforcement Point to each core Digital Twin service provides a modular and effective means of applying the NIST ZTA principles.
This approach ensures strong security boundaries by isolating services by default, minimizing potential impact in the event of a compromise, and maintaining strict access control.
Next steps:
Performance benchmarking, and scalability assessments.
Formal security validation, including attack simulations to fully evaluate the architecture¡¯s effectiveness in mitigating digital twin threats.
